EN2H-0220 GE51 R1005 

The switching differential corresponds to the set 
differential for automatic control and is symmetrical to the 
setpoint.  
 

 

NOTE 

The heat generator high limit prevails over the heat 
generator-switching differential and deactivates the heat 
generator in case it is exceeded. 

 

 

Application

 

Controller malfunctions (emergency mode) 
Breakdowns 
 

 

Termination

 

The return to the last selected operating mode is carried 
out with the "manual mode" / "emission measurement"  
key or the "Operating mode" key 

¢

 
 

4.1.2.8.2  Emission Measurement (Heating Controllers only) 

 

 

 

CAUTION

 

Emission Measurement has to be carried out by a 
technician only.  

 

 

 

 

 

By pressing "manual mode" / "emission measurement" 
key the heat generator runs for 20 minutes at the set 
maximum temperature limit. The remaining time is 
visualized as it passes. 

 
 

Function

 

The direct heating circuit pump is activated if the 
temperature in the heat generator exceeds 65 ºC. Any 
existing mixing valves carry out the control upon 
demand. 

 
 

 

Below 60 ºC the pump is blocked and existing mixing 
valves are closed. 

 
 

 

The mixing circuit pumps remain continuously in function. 

 
 

 

The DHW loading temperature remains continuously in 
function. 

 

 

 WARNING 

Danger of scalding because the DHW temperature may 
exceed the defined DHW setpoint. 

 

 

Application

 

Emission measurement via the chimney sweep.
